Detailed explanation-1: -The ADC takes the analog signal from the mic diaphragm/capsule at its input and converts that signal to digital information, which it then outputs. This converted digital audio signal is ultimately outputted by the microphone’s output, and thus the microphone is said to be “digital.”

Detailed explanation-2: -In electronics, an analog-to-digital converter (ADC, A/D, or A-to-D) is a system that converts an analog signal, such as a sound picked up by a microphone or light entering a digital camera, into a digital signal.

Detailed explanation-3: -The sound waves are converted into electrical signals by a microphone and transmitted in analog or digital form via the telephone network.
